With this one, I'm not really confident enough to give a R-b. I couldn't
find a problem, but I suppose it's more a case of "looks plausible
enough, we'll see what breaks". And while scsi is managable enough that
I could in theory invest a few more hours, we'll get more changes of the
same type anyway when merging the full removal of the AioContext lock
and reviewing all of that in detail will be impossible.
